I also wouldn't suggest used. You don't get a good deal on them till they are 10-20 years old and by then, you can look to be replacing parts regularly. Newer used that are less than 5 years old are almost always nearly the same price as new, many times asking as much or more than they cost new when bought. The funny thing is many of them are getting those prices so negotiating a better price is not to great either. If you have a good credit line, you can get 0% financing on most new tractors which is worth a few thousand over new that would be 5-10% or more to finance. You can also roll all of your equipment purchased at the time of sale into the 0% finance so that is also worth some bucks.
Don't forget to price some of the LS tractors. There should be some dealers nearby and they are generally a few thousand less than all the other brands and have better warranty than most others especially the Kubota with 1 year vs a 5 year engine/powertrain on the LS and I think 2 year bumper to bumper warranty. And they come with standard options that most other brands charge for like 2 rear remotes, telescopic lower 3 PH links.
